Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0050]In addition, if there are descriptions involving "first", "second" ...

Abstract

The invention discloses a reagent disc structure and a sample analyzer. The reagent disc structure comprises a reagent disc, a first driving part and a second driving part, the reagent disc is used for bearing a reagent bottle and a magnetic bead bottle, and magnetic bead gear teeth are arranged on the periphery of the magnetic bead bottle; the first driving piece is connected with the reagent disc and drives the reagent disc to rotate so as to drive the reagent bottles and the magnetic bead bottles to revolve; a blending gear is arranged at the output end of the second driving part and used for being in meshed connection with the magnetic bead gear teeth, and the second driving part drives the blending gear to rotate so as to drive the magnetic bead bottle to rotate. By controlling the rotating speed of the uniform mixing gear, the magnetic bead bottles are differentially driven to rotate, the rotating speed of the reagent disc can be increased while the magnetic bead bottles are kept in a stable rotating speed interval, and meanwhile, the diameter of the reagent disc can be increased to provide more reagent positions for placing more reagent bottles, so that the high-speed time sequence requirement is met.

Description

technical field [0001] The invention relates to the technical field of medical immune analysis, in particular to a reagent disc structure and a sample analyzer. Background technique [0002] In related technologies, there are mainly two schemes for the structure of the reagent disc: one is that the circumference of the reagent box is evenly distributed to rotate, since the rotation speed of the magnetic bead bottle needs to be within a stable range to ensure that the magnetic beads will not be damaged by the impact or the reagent will not be damaged. Liquid will be splashed, the rotation speed of the reagent disc and the diameter of the reagent disc affect the rotation speed of the magnetic bead bottle, which limits the speed of the reagent disc or the number of reagent positions. However, as the market demand for high-speed chemiluminescence instruments expands, the number of reagent positions in the instrument also needs to be expanded accordingly to meet the high-speed ti...
